ANCHOR-PIN.

Specification of Letters Patent.

Patented Mar. 31, 1914.

Application filed January 4, 1910. Serial No. 536,298.

To all whom it may concern:

Be it known that I, ISAAC M. FRY, a subject of the King of England,residing at the village of Maymont, in the Province of Saskatchewan andDominion of Canada, have invented new and useful Improvements inAnchor-Pins, of which the following is a specification.

The invention relates to an improved anchor pin adapted to be used fortethering cattle, or the like.

The main object of the present invention is the provision of an anchorpin which may be readily inserted into the ground without necessitatingthe usual driving operation and which when inserted tends materially toresist any lateral strain in so far as withdrawing the pin is concerned.

The invention in its preferred details of construction will be describedin the following specification, reference being had particularly to theaccompanying drawings, in which Figure 1 is a perspective of theimproved pin, the wrench bar being omitted. Fig. 2 is a bottom plan viewof the wrench member. Fig. 3 is a to plan view of the pin.

Referring particu arly to the accompanying drawings, the improved anchorpin comprises a body 1 which may be of any desired length or sectionalarea, said body being preferably circular in section and graduallytapering from the upper to the lower end. At the lower end the body 1 isprovided with a spear point 2 which point is circular in section and inthe maximum transverse dimension materially greater than the transversedimension of the smaller end of the pin. At the opposite or remote endthe body 1 is provided with a transversely disposed disk 3 having adiameter materially greater than the diameter of the adjacent end of thebody. Beyond the disk there is arranged a concaved bearing projection 4:arranged in alinement with the body of the pin and terminating at itsupper end in an angularly shaped head 5, preferably of conventional nutform. An eye 6 is connected by a swivel connection 7 to a ring 8encircling the bearing projection 4:, the connection between the ringand bearing being comparatively loose to permit free movement of the eye6 on said bearing as a center.

In connection with the pin described I utilize a wrench bar comprisingan elongated bar like member 9 centrally formed with a socket 10 to moreor less loosely fit the head 5 of the pin. One terminal of the bar isformed with an opening 11 designed to be connected to the ring 6 whenthe bar is in place by any appropriate flexible connector. The oppositeend of the bar 9 is formed with an opening 12 to receive the ends ofatether rope, or the like.

In applying the pin the latter is forced into the ground by a turningmovement secured through the medium of the bar 9 in cotiperation withthe head 5. The pin will finally seat itself with the disk in closecontact with the surface of the ground, after which the picket rope maybe attached to the opening 12 and tightened in any usual or desiredmanner. The point 2 serves in a measure to prevent withdrawal of thepin, while the disk serves to effectively prevent endwise strain on thebar 9 from tilting or inclining the pin toward such strain, therebyserving to maintain a more or less solid connection of the pin with theground at all times. The use of the bar brings any strain which may bebrought to bear upon the anchor pin in a direct line at right angles tothe length of the pin, as the connection between the bar and picket ropeis some distance beyond the pin proper and therefore the strain istransmitted to the pin by the bar, and the latter is of course at rightangles to the bar the connection between the bar and eye 6 prevent-ingdisconnection of the bar and pin and at the same time permit-ting thelifting of the bar from the head 5 if desired in applying or removingthe pin. The pin is of course to be made of any desired material and inany size best adapted for the purpose for which it is designed.

Having thus described the invention, what I claim as new, is

A picket pin consisting of a body having an intermediate conical portionwith a smooth exterior surface and which is circular in transversesection throughout itslength, said body having at the smaller end ofsaid intermediate portion a conical spear portion which is of greatertransverse diameter than the smaller end of the said intermediateportion and of less transverse diameter than the larger end thereof,said spear portion having a smooth exterior sur- In testimony whereof Iaflix my Signature face and being globular at one end and proin presenceof two Witnesses.
